This week we’re celebrating our 31st anniversary at National Aquarium, Baltimore, and we want you to join the fun!

Monday, August 6: Is your birthday also in August? On August 6, anyone who has an August birthday gets in FREE! Must present identification at the onsite ticket center to verify birthday. Plus, enjoy a free piece of birthday cake in the Aquarium’s Harbor Market Kitchen (while supplies last).

Wednesday, August 8: Meet Nickelodeon’s The Backyardigans! They’ll make a special appearance from 10 a.m.–2 p.m., and the first 200 guests will receive a free photo. We’ll also have fun games and crafts going on all day. Plus, enjoy a free piece of birthday cake in the Aquarium’s Harbor Market Kitchen (while supplies last).
